Tina Fey raps on Donald Glover's new mixtape

With the end of "30 Rock"in sight, Tina Fey is no doubt weighing her options for what she wants to do with her career next. She could always star in another movie, write another book or create another TV series. But on the 4th of July, she presented fans with a surprising new possibility: rapper.

On Wednesday, "Community's" Donald Glover released a mixtape for free download through his website under his rap name Childish Gambino. The album, called "Royalty," features a host of guest rappers including RZA, Ghostface Killah, Beck and lesser known performers, such as Danny Brown and Schoolboy Q. And yes, Glover's old "30 Rock" boss also makes her rapping debut.

Fey appears at the end of the album's final track, titled "Real Estate," rapping, "Yeah, we in here, we in this thing/ Gambino is forever, royalty is forever... This is the part where most people would say something crazy and drop the n-word after it / Not going to. Not gonna do that. Don't feel comfortable!"

What's the connection between Fey and Glover? Besides both having their shows on NBC on Thursday nights, Glover was a writer for "30 Rock" during the show's first two seasons. He left when he joined the cast of"Community."

"Royalty" is the follow-up to Glover's debut studio album, "Camp," which was released last year to largely positive reviews.

"Community" and "30 Rock" are returning to the NBC schedule for abbreviated 13-episode final seasons.
